• Tree sensors track urban growth, flowering and more

    24 days ago - By Phys

    Low-cost "tree fitbits" can pinpoint the precise timing of tree activities, like spring bloom or autumn leaf change, according to a new CU Boulder study. Researchers outfitted two East Boulder ash trees with high-resolution accelerometers, efficiently tracking how the trees responded to changing seasons. And in the coming years, arborists could efficiently monitor trees by the thousands with this technology-ultimately giving researchers insight into how tree phenology is changing with a warming climate.
